A project was conducted to develop and validate criterion-referenced test items for the following vocational education programs: child care worker, machine shop, electronics, drafting, and automobile mechanics. For each of the programs, the following activities took place: a project coordinator was assigned, subject-area instructors and a test construction expert were selected to participate in the test item development workshop, existing material was identified, a test item development workshop was conducted, tests were submitted for validation by test-construction experts, suggested changes were incorporated and field tested at various sites within Missouri, additional revisions accommodated field test results, and copies and computer disks of the tests were prepared for use during an inservice meeting of the Missouri Vocational Association. The tests are suitable for use by secondary schools, vocational-technical schools, junior colleges, and other institutions of higher and special education. The materials are expected to be used in more than 400 Missouri school districts. (Appendixes, which make up more than half the document, include the following: agenda for the machine shop criterion-referenced test development workshop; information on writing test items, including suggestions for using the cognitive, affective, and psychomotor domains; a matrix for linking objectives to test items, advantages and disadvantages of various types of test items; rules for writing true-false, matching, and multiple-choice items, and performance checklists; and steps in writing test items and checklists for Vocational Instructional Management Systems competencies.)
